Answer:
f(n) = a+200(n -1)
Step-by-step explanation:
The constant difference between terms indicates the sequence is an arithmetic one. The explicit formula for an arithmetic sequence is ...
an = a1 + d(n -1)
where a1 is the first term and d is the common difference.
Your first term is "a", and your common difference is 200, so the n-th term of the sequence is ...
an = a + 200(n -1)
Written as a function of n, this is ...
f(n) = a + 200(n -1)
_____
Based on the problem description, we cannot tell how n relates to time, so we have created an f(n) that gives the same result as the recursive definition of f(n).
Answer:
C
Step-by-step explanation:
The lines mean the distance away from 0. When i say lines, I mean the two "l" that accompany the numbers. I forgot what there called (good job me).
Since we want to know how far apart they are, we need to add them.

Answer:
2X-1
Step-by-step explanation:
as far as i got
Perimeter is the sum of all the sides. So we can set up an equation:
Now solve for 'x', combine like terms:
When it comes to terms with variables it's just like normal addition but we keep the variable:
So we have:
Add:
Subtract 7x to both sides:
Subtract 4 to both sides:
Divide 5 to both sides:
